CHURN.

SPECIFICATION forming par-t of Letters Patent No. 369,426, datedSeptember 6, 1887.

A ppleation led Octoherf), 1856. Serial No. 216,768.

To @ZZ whom, it may concern:

Be it known that I, CHARLES BENNET, a citizen ol the United States,residing at Maa chester, Dearborn county, Indiana, have invented new anduseful Improvements in C hurns, of which the following is aspecification.

My invention relates to churns, its object being to provide an efiicientmechanism for Io the agitation and aeration7 ofthe cream in order teobtain a more speedy and larger yield of butter.

To this end it consists in the construction of the churn and itsoperating mechanism, as

i5 hereinafter more fully described.

In the accompanying drawings, illustrating my invention, Figure l is aside elevation of the apparatus, showing the churn in section; and Fig.2, an end elevation ofthe same, showing the churn in section.

Referring now to the drawings, in which the parts herein referred to areindicated by the letters of reference, A designates the body of thechurn, which is preferablya boX oi' rectangular form with a removablecover.

B designates the dashen which is in paddle form, as shown, pivoted tothe top of the churn at c, and having a handle, d, projecting upwardthrough the cover.

The entire apparatus is mounted on a base- !"rame, F, of convenientconstruction supporting the driving apparatus, presently to bedescribed, and the churn proper.

The churn-body is intended to have-are ciprocating horizontal motion, towhich end it is provided with `friction-rollers fr o at one side,haviuga rolling bearing upon the frame F, and supporti ngbars a a projected inthe same axial line at opposite sides of the churn and 4o supported insliding bearings upon or in brackets b b, secured to the frame F. Themode of mounting the churn upon the frame F may, however, be Varied, aspreferred, it being essential only to provide for the reciprocatingmotion referred to.

rlhe driving mechanism is as follows: Upon the platform F, in uprights7i; 7;, is mounted a driving-shaft, h., carrying a band fly-wheel, l.The shaft is provided at one end with an operating handcrank, 71,', andat the other with a driving-crank, is?, the latter being connected (Nomodel.)

with the following mechanism: To the front of the churn is attached apivotal link, g, project-ing to a point in line with the crank if, andat the top of the churn and projecting tothe same vertical line with thelink'g is a connecting-rod, e, which has a detachable but temporarilyrigid connection with the upper end ofthe dasher-arm d. The rod e andlink g are terminally connected by a parallel rod, ffwhich is pivotedmidway to the crank h2. This mechanism, as will be observed, produces adouble effect upon the churn, to Wit: a horizontal reciprocation of thechurn and a vibratory or pendulous motion ofthe dasherin relativelyopposite directions. These opposing movements of the churn and itsdasher are assisted by the outward curving surface of the dasher and itsupper part, by which the liquid contents of the churn are thrownrelatively outward at each side and prevented from meeting .over the topof a dasher or passing out through the aperturein the cover.

There may be added an alternative driving mechanism for operatingthedasher alone, but more rapidly, as follows: A counter-shaft, m, ismounted at the opposite end of the platform F, driven by a band, Z',from the flywheel Z, and carries a crank, m. The connecting-rod S0 e,being shifted to the position shown in dotted lines and resecured a gainrigidly to the dasherarm d, is terminally connected with the crank m bylink It will now be evident that the rotation of the counter-shaft in,will vibrate the dasher B without moving the churn A, which latter,however, is made fast by setsorews s, provided at its bracket-bearingsb. The belt-connection Z' is arranged to multiply speed, so as to givethe dasher a more rapid 9o motion than before. v

lt is intended by thus introducing two dif- :ferent driving mechanismsto adapt the apparatus to best results for both summer and winter use.Thus, in winter, when the temg5 perature renders the operation ofbutter-making more sluggish and difficult, the rst-described mechanismmay be used, producing a more violent agitation of the churn contents,and in summer the last-described mechanism roo may be employed; butthough preferable I do not regard the last-described mechanism asessential, and it may be wholly omitted if desired and the samepractical effect produced by disconnecting the link g from the parallelrodf, securing the churn by the set-screws s, 5 anddrevolving the shafth with the rapidity desire I claim as my invention and desire to secureby Letters Patent of the United States- 1. The combination, in apower-churn, of a 1o churn-body, A, pivoted dasher B, rod-con ncctions ef g, and the driving-crank h2, substantially as set forth.

2. In a power-churn, the combination of a platform, F, provided withbrackets I), the 15 churn-body provided with friction-rollers r,
